Bintje
Bintje is a middle-early ripening potato variety bred in the Netherlands by the Frisian schoolmaster K.L. de Vries in 1904 from (Munstersen x Fransen) and marketed for the first time in 1910. The name of the potato, a diminutive of Benedict, was borrowed from one of his former students. Bintje plants are medium-sized and erect, with purplish stems, dark green leaves and white flowers. Bintje produces large oval-shaped tubers with pale yellow skin and yellow flesh. It has shallow eyes. The sprouts are purplish. This high-yielding variety is widely grown in Europe and North Africa. It is used for boiling, baking, and for fries, mashed potato and potato chips. It is the most widely cultivated potato in France and Belgium. Bintje is immune to Potato virus A. It has moderate resistance to Potato leafroll virus. It is susceptible to netted scab, common scab, Fusarium dry rot (''Fusarium oxysporum''), potato wart (''Synchytrium endobioticum''), Potato virus X, Potato virus Y, and la ...

Fusarium Dry Rot
''Fusarium'' dry rot is one of the most common potato diseases. It is caused by fungi in the genus ''Fusarium''. This fungi causes a variety of colored rots in potatoes. This pathogen, while having both a sexual and asexual form, stays in an asexual cycle due to the way it spreads. Preferring warmer climates, it is not uncommon to find this pathogen in the northern United States where it has been reported to affect yield as much as 60%. Hosts and symptoms ''Fusarium'' dry rot of potato is a devastating post-harvest losses (vegetables) disease affecting both seed potatoes and potatoes for human consumption.Rowe, R.C., Miller, S.A, & Riedel R.M. ''Fusarium'' Dry Rot and Seed Piece Decay of Potato. Retrieved from http://www.oardc.ohio-state.edu/sallymiller/extension/factsheets/fuspotato.pdf Dry rot causes the skin of the tuber to wrinkle. The rotted areas of the potato may be brown, grey, or black and the rot creates depressions in the surface of the tuber. Seed pieces may rot complet ...

Hardegarijp
Hurdegaryp ( nl, Hardegarijp) is a village in the northern part of the Netherlands, in the municipality of Tytsjerksteradiel. Its history dates back to at least the 13th century. It had a population of around 4,788 in January 2017. In Dutch the village is called ''Hardegarijp'', Hurdegaryp is its West Frisian and official name. History The village was first mentioned in 1401 as Herdegaryp. The etymology is unclear. Originally the centre of the village was located further south. In 1830, the road to Leeuwarden was built. The Hurdegaryp railway station followed in 1866, and the centre of the village moved towards to the road and station. The Dutch Reformed church was built in 1711 and has a wooden tower. It was a replacement for a 13th century church. Up to 1829, the Grovestins, a fortified tower was located to the south of the village. Hurdegaryp was home to 624 people in 1840. From the 1960s onwards, it became a suburb of Leeuwarden. In 2017, five tiny houses measuring 3 by 9 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytophthora Infestans
''Phytophthora infestans'' is an oomycete or water mold, a fungus-like microorganism that causes the serious potato and tomato disease known as late blight or potato blight. Early blight, caused by ''Alternaria solani'', is also often called "potato blight". Late blight was a major culprit in the 1840s European, the 1845–1852 Irish, and the 1846 Highland potato famines. The organism can also infect some other members of the Solanaceae. The pathogen is favored by moist, cool environments: sporulation is optimal at in water-saturated or nearly saturated environments, and zoospore production is favored at temperatures below . Lesion growth rates are typically optimal at a slightly warmer temperature range of . Etymology The genus name ''Phytophthora'' comes from the Greek –(), meaning : "plant" – plus the Greek (), meaning : "decay, ruin, perish". The species name ''infestans'' is the present participle of the Latin verb , meaning : "attacking, destroying", from which we ...

Potato Virus Y
Potato virus Y (PVY) is a plant pathogenic virus of the family ''Potyviridae'', and one of the most important plant viruses affecting potato production. PVY infection of potato plants results in a variety of symptoms depending on the viral strain. The mildest of these symptoms is production loss, but the most detrimental is 'potato tuber necrotic ringspot disease' (PTNRD). Necrotic ringspots render potatoes unmarketable and can therefore result in a significant loss of income. PVY is transmissible by aphid vectors but may also remain dormant in seed potatoes. This means that using the same line of potato for production of seed potatoes for several consecutive generations will lead to a progressive increase in viral load and subsequent loss of crop. An increase in potato plant infection with viruses over the past few years has led to considerable losses to the South African potato industry. The increased rate of infection may be attributed to several factors. These include a mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potato Virus X
Potato virus X (PVX) is a plant pathogenic virus of the family ''Alphaflexiviridae'' and the order ''Tymovirales''. PVX is found mainly in potatoes and is only transmitted mechanically. There are no insect or fungal vectors for this virus. This virus causes mild or no symptoms in most potato varieties, but when Potato virus Y is present, synergy between these two viruses causes severe symptoms in potatoes. The virion has helical symmetry and a deeply grooved, highly hydrated surface and is made of a single-stranded positive-sense RNA genome of approximately 6.4 kb. This is wrapped in approximately 1300 units of a single coat protein (CP) type, with 8.9 CP units per helix turn. The genome is capped at the 5′-end and poly-adenylated at the 3′-terminus. It contains five open reading frames (ORFs) encoding five proteins: the RNA-dependent RNA Polymerase (RdRP), the movement proteins encoded by three overlapping ORFs that form the Triple Gene Block module (TGBp1, TGBp2, and TGBp3), ...

Synchytrium Endobioticum
''Synchytrium endobioticum'' is a chytrid fungus that causes the potato wart disease, or black scab. It also infects some other plants of the genus ''Solanum'', though potato is the only cultivated host. Systematics Traditionally, ''Synchytrium endobioticum'' has been placed to the subgenus ''Mesochytrium'', but it has been suggested that on the basis of the mode of germination it should be transferred to the subgenus ''Microsynchytrium''. It was first identified and studied by Vera Charles. The New Zealand scientist Kathleen Maisey Curtis also studied ''Synchytrium endobioticum'' for her doctoral thesis that, in 1919, resulted in her being recognised as producing groundbreaking research on the organism's pathology. At least 18 pathotypes of the fungus exist, most of them with quite limited ranges in Central Europe. The most widely distributed is the pathotype 1. Morphology Like some other Chytridiales, ''Synchytrium endobioticum'' develops no mycelium. The fungus produces a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fusarium Oxysporum
''Fusarium oxysporum'' (Schlecht as emended by Snyder and Hansen), an ascomycete fungus, comprises all the species, varieties and forms recognized by Wollenweber and Reinking within an infrageneric grouping called section Elegans. It is part of the family Nectriaceae. Although their predominant role in native soils may be as harmless or even beneficial plant endophytes or soil saprophytes, many strains within the ''F. oxysporum'' complex are soil borne pathogens of plants, especially in agricultural settings. Taxonomy While the species, as defined by Snyder and Hansen, has been widely accepted for more than 50 years, more recent work indicates this taxon is actually a genetically heterogeneous polytypic morphospecies, whose strains represent some of the most abundant and widespread microbes of the global soil microflora. Genome The ' family of transposable elements was first discovered by Daboussi ''et al.'', 1992 in several ''formae speciales'' and Davière ''et al.'', 2001 ...

Potato
The potato is a starchy food, a tuber of the plant ''Solanum tuberosum'' and is a root vegetable native to the Americas. The plant is a perennial in the nightshade family Solanaceae. Wild potato species can be found from the southern United States to southern Chile. The potato was originally believed to have been domesticated by Native Americans independently in multiple locations,University of Wisconsin-Madison, ''Finding rewrites the evolutionary history of the origin of potatoes'' (2005/ref> but later genetic studies traced a single origin, in the area of present-day southern Peru and extreme northwestern Bolivia. Potatoes were domesticated there approximately 7,000–10,000 years ago, from a species in the ''Solanum brevicaule'' complex. Lay summary: In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated. Potatoes were introduced to Europe from the Americas by the Spanish in the second half of the 16 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
